Abstract (en)

[origin: EP3766536A1] A device includes a container (100) for accommodating a medicament, a pressure route (200) and a valve (400). The pressure route (200), disposed in the container (100), includes an extending pathway (230), a pressure-route inlet (210) connected with a connecting port (300), and a pressure-route outlet (220) extending toward a container bottom. The valve (400) includes a first through hole (410) connecting spatially the pressure-route inlet (210) and outlet (220), and a valve body (420) dividing the extending pathway (230) into a pressure-in pathway (231) and a pressure-out pathway (232). The device can convey the medicament such as a hemostatic agent more stably and smoothly to effectively avoid blocking upon a field of vision of an endoscope by the disturbed medicament while hitting a target tissue. Thereupon, the medicament can be provided more precisely, continuity of an endoscopic surgery can be improved, efficiency of hemostasis can be enhanced, and also surgery time can be substantially shortened.
